FIELD OF THE INVENTION

The present invention relates to systems and methods for managing and publishing content and more specifically to managing and publishing managed content.

BACKGROUND

A content management system is a system configured to enable the management and publishing of content stored using the content management system. Content management systems organize and store a variety of content, such as documents, image data, video data, and audio data utilizing a back-end storage system. Content management systems also provide functionality to centralize the publishing of those documents, such as via one or more web sites. By providing centralized functionality for the publishing of documents, a content management system provides a convenient way to host and manage a variety of web sites from a single back-end storage system.

The Internet is a global system of interconnected computer networks. Varieties of services are provided on the Internet, including websites. Websites include a variety of content, such as text, pictures, audio data, video data, and other interactive content. Web sites are typically hosted using content servers and a web browser is an application that enables a user to receive, view, and interact with a websites hosted on content servers. A variety of web browsers are commonly used to view websites, including Internet Explorer from Microsoft Corporation of Redmond, Wash. and the Chrome browser from Google, Inc. of Mountain View, Calif.

Many documents, including web pages within a website, are written using the Hypertext Markup Language (HTML). A HTML document contains a set of nested tags. HTML tags include data stored in the tag, either as a property of the tag or between an opening tag and a closing tag. Web browsers do not display the HTML tags; rather, web browsers are configured to parse a HTML document and render one or more web pages including the information stored in the HTML tags. Cascading Style Sheets (CSS) are used to describe the formatting and display of a document when it is rendered. CSS can be used to describe the formatting of a variety of documents, including HTML documents and other documents, such as documents written using the Extensible Markup Language (XML). A single document can have a variety of associated CSS, so that the document can be rendered in a variety of ways depending on the capabilities of the device used to display the document. For example, a HTML document can be rendered with one format in a web browser on a desktop computer using a CSS designed for a desktop browser, while the same HTML document can be rendered in a second format in a web browser running on a mobile phone using a second CSS designed for a mobile browser.

Many web pages utilize scripts in order to provide flexibility in the creation and display of a web page. Scripts can be written in a variety of languages, including JavaScript by the Mozilla Foundation of Mountain View, Calif. and ECMAScript, standardized as ECMA-262 by ECMA International of Geneva, Switzerland. Web browsers are configured to parse and execute scripts contained in web pages. These scripts can control the appearance of a web page, customize the content according to the preferences of a user viewing the web page, and allow for data to be received using the web page. Scripts can be server-side, where the script is run on a content server, or client-side, where the script is run using the web browser receiving the script.

DETAILED DESCRIPTION

Turning now to the drawings, systems and methods for managing and publishing managed content in accordance with embodiments of the invention are illustrated. Versioned content management server systems in accordance with embodiments of the invention are configured to receive, store, and transmit managed content. In a variety of embodiments, managed content includes content data and a set of versioning data, where a subset of the versioning data can be combined with the content data to create a version of the managed content. In a number of embodiments, versioning data is stored using content version metadata associated with the managed content. In many embodiments, one or more versions of managed content can refer to pieces of unmanaged content (i.e. content located on remote servers and/or content that does not include versioning data that can be utilized to generate alternative versions of the content). The unmanaged content can be stored using the versioned content management server system and/or an external unmanaged content source.

Versioned content management server systems in accordance with many embodiments of the invention can receive modified versions of managed content and track the differences between currently stored managed content and the received modified content. The tracked differences can be included in the versioning data for the managed content. In this way, versioned content management server systems can simultaneously store a number of versions of the managed content and transmit an appropriate version of the managed content in response to a request for (a particular version of) the managed content. In a variety of embodiments, versioned content management server systems include content version decision data associated with one or more pieces of managed content describing one or more conditions associated with providing versions of the managed content in response to a content request. Content requests can be received from a variety of devices, including content delivery server systems and content display devices; other devices can request content from and/or provide content to versioned content management server systems as appropriate to the requirements of specific applications in accordance with embodiments of the invention.

Methods for receiving, storing, and transmitting managed content in accordance with embodiments of the invention are discussed below.

Providing Managed Content

By utilizing managed content and associated content version metadata, versioned content management server systems in accordance with embodiments of the invention are capable of hosting and transmitting multiple versions of the managed content in response to different requests for content. This allows versioned content management server systems to host both a variety of different pieces of managed content and multiple versions of each piece of managed content simultaneously. A process for identifying and transmitting managed content in accordance with an embodiment of the invention is illustrated in FIG. 3. The process 300 includes receiving (310) a content request. Managed content is identified (312). Content is generated (314) and transmitted (316).

In many embodiments, a content request is obtained (310) from a content display device configured to display content and/or a content display server system configured to retrieve content and provide the retrieved content to content display devices. In a number of embodiments, the obtained (310) content request identifies (312) the managed content and/or the desired version of the managed content. In several embodiments, identifying (312) managed content includes utilizing content version decision data along with the obtained (310) content request. In a number of embodiments, identifying (312) managed content is based on performance data associated with the managed content. Content can be transmitted (316) via any number of protocols and/or techniques as described above.

In a variety of embodiments, generating (314) content includes identifying (312) one or more pieces of managed content and utilizing those pieces of managed content. Identifying (312) the pieces of managed content can be based on content version metadata associated with the managed content. In many embodiments, generating (314) content includes merging a piece of managed content with one or more content changes described in content version metadata associated with the piece of managed content. Processes for merging pieces of content to generate (314) content are described further below.

Processes for receiving, storing, and presenting alternative versions of managed content in accordance with embodiments of the invention are discussed below.

Obtaining and Storing Managed Content

When hosting content, it is often desirable to store a variety of versions of the content. By storing a variety of versions, different presentations and/or revisions of the content can be transmitted in response to requests for the content. Additionally, if any of the revisions of the content are defective, requests for the defective content can easily be redirected towards a non-defective revision of the content in real time. Versioned content management server systems in accordance with embodiments of the invention are configured to host a variety of versions of managed content and transmit versions of the hosted content in response to requests for content. A process for storing managed content in accordance with embodiments of the invention is illustrated in FIG. 4. In a variety of embodiments, content is locked (410). Content is obtained (412). In several embodiments, managed content is located (414). Version information is identified (416). Content version metadata is generated (418). Managed content is stored (420).

In several embodiments, locked (410) content is associated with one or more pieces of author data, where the author data indicates a user and/or device authorized to modify the content. In a variety of embodiments, obtained (412) content includes obtained content version metadata describing versioning information regarding a piece of managed content. In a number of embodiments, obtained (412) content does not have any corresponding managed content. In many embodiments, managed content is located (414) using the obtained content version metadata associated with the obtained (412) content. In a variety of embodiments, managed content is located (414) by manually identifying a piece of managed content selected from one or more pieces of managed content identified as being similar to the obtained (412) content.

In many embodiments, version data is determined (416) based on the obtained content version metadata and/or differences between the obtained (412) content and the located (414) managed content. In several embodiments, content version metadata is generated (418) by manually merging conflicts between the obtained (412) content and the located (414) managed content. Conflicts can be automatically merged utilizing a variety of techniques, such as three-way merges, recursive three-way merges, fuzzy patching, weave merging, and rebasing, in accordance with embodiments of the invention. In a number of embodiments, the managed content and the content changes can be arranged in a hierarchical relationship and generating (314) content includes merging content changes with the managed content, where the generated (314) content utilizes the content changes having the managed content as a common ancestor in the hierarchical relationship. Other techniques, including those utilizing non-hierarchical relationships between pieces of content, such as directed acyclic graphs and ontologies, can be utilized as appropriate to the requirements of specific applications in accordance with embodiments of the invention.

In several embodiments, the content version metadata generated (418) includes performance data taken from the located (414) managed content. In a number of embodiments, the generated (418) content version metadata includes the determined (416) version data, the author data, the obtained content version metadata, and/or time information. Other data including, but not limited to, branch data, label data, check in/check out data, and merge data, can be included in the content version metadata as appropriate to the requirements of specific applications in accordance with embodiments of the invention. In a variety of embodiments, storing (420) managed content includes storing the generated (418) content version metadata and associating the content version metadata with the located (414) managed content using a hierarchical relationship and/or a graph-based relationship structure. In a variety of embodiments, storing (420) managed content includes unlocking the locked (410) content. Content can be unlocked by modifying the content version metadata associated with the locked (410) content.

A specific process for obtaining and storing managed content is described above with respect to FIG. 4; however, any number of processes for receiving and storing versioned content can be utilized in accordance with embodiments of the invention. Methods for presenting alternative versions of managed content and tracking the performance of managed content are discussed below.

Presenting Alternative Versions of Managed Content

Content developers often wish to present particular versions of content on particular days and/or test multiple versions of content in order to measure the relative effectiveness of the various versions of content. Versioned content management server systems in accordance with embodiments of the invention are configured to dynamically provide different versions of managed content based on one or more decision factors. A process for dynamically presenting alternative versions of managed content in accordance with embodiments of the invention is illustrated in FIG. 5. The process 500 includes obtaining (510) content version decision data. A content request is obtained (512). Managed content is located (514) and transmitted (516).

In a number of embodiments, the obtained (510) content version decision data includes one or more decision factors. Decision factors that can be utilized include the time of a content request, the number of times a particular version of one or more pieces of managed content are provided, the version or versions of the managed content to be transmitted, performance data associated with one or more versions of the managed content, and the device and/or user associated with a content request. Other decision factors can be utilized as appropriate to the requirements of specific applications in accordance with embodiments of the invention. In many embodiments, a content request is obtained (512) and/or managed content is located (514) utilizing processes similar to those described above. In several embodiments, the obtained (512) content request includes the time the request was made, the capabilities of the device providing the content request, and/or user data associated with the content request; other information can be included in the content request as appropriate to the requirements of specific applications in accordance with embodiments of the invention. In a number of embodiments, managed content is located (514) based on the obtained (510) content version decision data and the obtained (512) content request. In a variety of embodiments, the transmitted (516) content is a version of the located (514) managed content generated utilizing processes similar to those described above. In several embodiments, the transmitted (516) content is the located (514) managed content.

By way of example, by basing the version of the managed content to provide on the time of the request for content, a version of the located (514) managed content can be developed for events on particular days and times (such as holidays and other noteworthy events) in advance of the event and automatically presented in response to obtained (512) content requests on those identified days and times without taking any additional action. When the indicated time and/or event has ended, the original version of the content (or a newer version) is automatically transmitted (520) in response to obtained (512) content requests without any additional work necessary to either update the managed content or roll the managed content back to a previous version. As a second example, multiple variants for the same piece of managed content can be created in order to test the relative performance of the variants of the managed content. The obtained (510) content version decision data indicates the variants of the managed content to present and the desired criteria to transmit (516) a particular version of the located (514) managed content. In several embodiments, the criteria can include (but are not limited to) presenting certain versions of the located (514) managed content based on geolocation data indicating the location of the device from which the content request was obtained (512), the time at which the content request was obtained (512), and/or the number of times each version of the managed content has been transmitted (520). In this way, the obtained (510) content version decision data can be utilized to perform comparison testing of multiple versions of located (514) managed content, geographic-based targeting of content, and/or time-based targeting of content.

Although a specific process for presenting alternative versions of managed content is described above with respect to FIG. 5, any number of processes can be utilized in accordance with embodiments of the invention. Methods for associating performance information with versions of managed content in accordance with embodiments of the invention are discussed below.

Tracking Managed Content Performance

It is often useful to track the performance of various versions of managed content. The tracked performance data can be associated with the appropriate versions of the managed content and used to identify those versions that perform well and/or poorly. Versioned content management server systems in accordance with embodiments of the invention are configured to receive and store performance data associated with various versions of managed content. A process for associating performance information with one or more versions of managed content in accordance with embodiments of the invention is illustrated in FIG. 6. The process 600 includes obtaining (610) performance information. Managed content is located (612) and content version metadata is updated (614).

In a variety of embodiments, performance information is obtained (610) from content delivery server systems providing content to content display devices. In many embodiments, performance information is obtained (610) from a client display device. In several embodiments, the performance information is obtained (610) based on comparison testing of versions of managed content utilizing processes similar to those described above. In a number of embodiments, the performance information contains engagement data. Systems and methods for determining performance information for content that can be utilized in accordance with embodiments of the invention are disclosed in U.S. patent application Ser. No. 13/792,855, titled “Systems and Methods for Categorizing and Measuring Engagement with Content” and filed Mar. 11, 2013, the disclosure of which is hereby incorporated by reference in its entirety. In several embodiments, locating (612) managed content utilizes the obtained (610) performance information to identify the managed content and/or a version of the managed content. In a variety of embodiments, updating (614) the content version metadata includes associating the obtained (610) performance information with the located (612) managed content and/or one or more pieces of content version metadata associated with the located (612) managed content.

A specific process for tracking the performance of different versions of managed content is described above with respect to FIG. 6; however, any number of processes can be utilized in accordance with embodiments of the invention.

Although the present invention has been described in certain specific aspects, many additional modifications and variations would be apparent to those skilled in the art.
